Best Freeware Registry Cleaner

Registry cleaners are software programs that remove unnecessary entries from the Windows Registry. Registry cleaners are especially useful for removing registry entries that point to files that no longer exist.


CCleaner is a powerful and easy to use utility that cleans and optimizes your PC to ensure best performance. It can remove unused and temporary files from your system. It also prompts you to backup the registry before it makes changes, and includes a number of other useful tools.

Glary Utilities

Glary Utilities is not solely a cleaning app. You won’t find a “Cleaner” tab in the app anywhere and it doesn’t provide the controlled cleaning of app and browser data like CCleaner does.

What Glary does provide is a set of fantastic system management tools. There’s a 1-Click Maintenance mode that will check registry, shortcuts, startup apps, repair disk damage, and even remove spyware. All from a single click. Just running this 1-Click Maintenance will assure that your Windows ship encounters smooth sailing.
